^ What he said.

I2 engines rock side to side rather than fore and aft.

That's why they do the cylinders at the same time.

Triumph does a 270 crank on some models to give it more potato potato or whatever the hell produce item they have over there that sounds like an engine.

I read about BMW's balance rod solution that JM referenced. It's clever, no doubt.

But why not have one piston hitting TDC while the other hits BDC? That's how my Vee's 90-degree twin achieved balance without weights or rods. HD throws both pistons up and down together on their Vee, which creates their unique engine "experience."

I reject the inline twin engine for it's inherent design failures! All manufacturers should immediately cease and desist their construction forthwith and replace them with V-4s!
Big difference between a V and an inline Kenneth.

Harleys pistons stagger just a little due to the single pin crank giving it the potato sound.

I think think an inline would shake side to side like crazy if they did what you suggested.

Sure there is, all the designs have their own characteristics, benefits, disadvantages, etc. I was just hoping someone had the specifics as to why this engine was designed this way vs other I twins.
Most I twins have 360 degree cranks.

Some have 270s cuz they sound better.

When I was deciding on the CB I watched the Honda design team video, which has a segment with a former Japanese racer riding around on it. When I saw the bike In person the first time I was shocked at how small it was. I didn't realize the racer dude must be about 4' tall and 90 lbs. It's false advertising I tell you!
You could have deduced that once you knew he was a "former Japanese racer."
